Effect of Oscillation Parameters to Flow Field in the Pool during
During the oscillating twin-roll strip casting process, the quality of final products is directly influenced by the flow field distribution of molten metal in the pool. The variation in
Sand mold casting explosion : r/CatastrophicFailure
What happened was that the upper and lower parts of the mold, called "cope" and "drag" respectively, weren''t properly attached together. The hydrostatic pressure from the molten metal inside the mold broke whatever they had used to attach
Flow Transport and Inclusion Motion in Steel Continuous-Casting Mold
Clogging of the submerged entry nozzle (SEN) is a serious problem during the continuous casting of steel, due to its influence on the casting operations and product quality.
Strip & Pad Foundations
The depth a traditional strip foundation is generally equal to or greater than the overall wall width, and the foundation width is generally three times the width of the supported wall. The principle design features of a strip foundation are
Mold Simulator Study of the Initial Solidification of Molten Steel in
The surface quality of the continuous casting strands is closely related to the initial solidification of liquid steel in the vicinity of the mold meniscus, and thus the clear
Evaluation of Mold Electromagnetic Stirring in Slab Continuous Casting
DURING the slab continuous casting (CC) process, mold powder is added periodically to the top of mold and melts by the molten steel to form the liquid slag layer, which have the functions
Effect of strip feeding into mold on fluid flow and heat
Steel strip feeding into the mold during continuous casting is known as an innovative technology. The newly applied technology is designed to further improve the slab quality. To analyze the complex phase change
Numerical simulation of flow and solidification in continuous casting
The mold electromagnetic stirring (M-EMS) has been widely used in the continuous casting process to improve the surface quality, refine grain size, and reduce segrega-tion [1]. The
Mathematics simulation and experiments of continuous casting with strip
The paper establishes the mathematical model of heat transfer and temperature field of casting billet of steel strip feeding in continuous casting mold. Results show that if Plate
6 FAQs about [Pool-support strip foundation casting and mold explosion]
Does feeding strip affect inclusion distribution during solidification process of continuous casting?
A mathematical model was developed to numerically simulate the effect of feeding strip on inclusion distribution during solidification process of continuous casting slab. From the present study, the following conclusions can be drawn: There are a “lower recirculation” and an “upper recirculation” during conventional slab continuous casting.
What causes oscillation marks in a casting mold?
Some believed that it was caused by the slag flow, others believed it was related to the fluctuation of heat flux. Therefore, a two-dimensional continuous casting mold model was established in this study to investigate initial solidification of the shell and the formation of oscillation marks.
How to control slag pool depth in ULCs mold?
Thermal plasma melting furnace feeding facility has been developed to control the slag pool depth in the mold by increasing the melting rate. The proposed optimized range of slag pool depth was verified in a commercial trial by realizing thickness control of slag pool depth during ULCS production.
What causes defects in a continuous casting process?
A variety of complex phenomena have occurred during the continuous casting process, including flow, heat transfer and solidification, which interacts with each other. Hence, some defects are inevitably caused during this process, such as oscillation marks, slag inclusion, segregation [ 1, 2, 3 ].
What is the slag pool depth of ULCs casting?
The slag pool depth was controlled, targeted at 0.39 with 0.36 LSL and 0.46 USL. Mold flux consumption of mold powder of ULCS casting is about 0.12 to 0.15 kg/m 2 with 6 to 9 mm of slag pool depths.
What is the pressure at the mold top?
The pressure at the mold top was considered as atmospheric pressure (101,325 Pa), the temperature was considered as room temperature (303 K). A velocity inlet condition was applied to the nozzle inlet, and inlet velocity value was determined by the mass conservation as Eq. 9. $$ {v}_ {in}=\frac { {v}_ {c}\bullet {A}_ {out}} { {A}_ {in}}$$
